FIELD

The present teachings relate to a leash attachment that expels liquid into a built-in cup for a leashed animal to drink from.

INTRODUCTION

Owning an animal that requires a leash is no small feat. There are many issues to consider when keeping such a pet, one of which is stopping for liquid breaks while out walking, which can be a nuisance.

While there are current devices that provide liquid to leashed animals, their usage can be cumbersome. An ergonomically designed and easy to use device that delivers liquid to leashed animals without the owner having to stop and fumble for an alternate device or solution is ideal. This leash attachment offers hydration for the leashed animal, providing an effective solution every pet owner can appreciate.

SUMMARY

The present teachings include a leash attachment that comprises a housing that has a top surface that is downwardly angled. Within the housing is a liquid reservoir that holds a liquid. A fill hole is also in the housing and allows liquid to be added to the reservoir. A flip open cup rests on the top surface of the housing. A first pair of detents, attached to the housing, keeps the flip open cup in the non-use, or closed position. In effect, the first pair of detents keeps the flip open cup from unwantedly swinging open and outward. A trigger is connected to a dispensing mechanism that expels the liquid. A leash connects to the leash attachment through the leash hole, with a cam that secures the leash in place. A second pair of detents keeps the cam in place. When pressed, the second pair of detents releases the cam from the leash attachment.

In accordance with a further aspect, the dispensing mechanism comprises a body and at least one straw. When there is liquid in the liquid reservoir, depressing or deploying the trigger aspirates or sucks liquid into the at least one straw, through the body, and out through a nozzle. The liquid travels through a first end of the at least one straw and exits through a second end of the at least one straw that is connected to the nozzle.

In accordance with yet another aspect, the housing comprises a grip that allows a user to easily grasp the leash attachment. The grip makes it easier to deploy the trigger while still holding the leash attachment.

In accordance with yet another aspect, the flip open cup swings outward to an open position. From the open position, the flip open cup can be filled by liquid coming from the nozzle.

In accordance with yet another aspect, the cam is a rolling structure that is positioned within the leash hole. A leash inserted through the leash hole rolls along ridges of the cam, securing the leash.

In accordance with yet another aspect, the top surface of the housing is angled downward. The angle downward is between 15 and 45 degrees in relation to the ground when the leash attachment is held by the user. The flip open cup rests on the angled portion of the housing when in the closed position, or when not in use.

Any type of leash, with the exception of chain link and retractable leashes, can be accommodated by the leash attachment as long as it fits through the leash hole. Leashes made of leather, nylon, or rope are all suitable. The leash attachment can remain on the leash or be easily removed from the leash.

In accordance with yet another aspect, the trigger is connected to the dispensing mechanism; a body and at least one straw comprise the dispensing mechanism. Depressing or deploying the trigger sucks liquid into a first end of the at least one straw, through the body and out through a second end of the at least one straw, which is connected to the nozzle. The liquid that exits the nozzle is expelled into the flip open cup when the flip open cup is in the open position. The liquid is expelled towards the distal end of the flip open cup (i.e. the part of the flip open cup farthest away from the user when the flip open cup is in the open position). The liquid exiting the nozzle can also be directed at the leashed animal, at another animal, or at the ground when the flip open cup is in the closed, or non-use, position.

In accordance with yet another aspect, the user fills the liquid reservoir with liquid through the fill hole. A cap covers the fill hole so liquid cannot leak through the fill hole.

In accordance with yet another aspect, leash attachment placement in relation to the leash is of critical importance. If the leash attachment is too close to the proximal end of the leash, i.e. the end of the leash held by the user, the leash attachment may obstruct the leash. If the leash attachment is too far away from the proximal end of the leash, there is too much leash between the proximal end of the leash and the leash attachment; the owner would have to carry the slack part of the leash, which may be cumbersome. There is an optimal range for the distance of the leash attachment from the proximal end of the leash. 6 inches plus or minus 2 inches is the optimal range. In essence, between 4 inches and 8 inches is the optimal distance between the leash attachment and the proximal end of the leash.

In accordance with yet another aspect, liquid exiting the nozzle is pointed towards the distal end of the flip open cup. This will allow the liquid to flow downward into the flip open cup when the cup is in the open position. Pointing the nozzle toward the proximal end of the flip open cup when dispensing liquid from the nozzle is of no use, since the flip open cup must be fully lowered to the open position for ease of use for the leashed animal. Not fully lowering the flip open cup makes it more difficult for the leash animal to drink from the flip open cup.

In accordance with yet another aspect, the cam secures the leash and locks the leash into place.

In accordance with yet another aspect, a funnel directs unused liquid in the flip open cup back through the fill hole back into the liquid reservoir.

In accordance with yet another aspect, a locating pin allows for easy assembly of the flip open cup to the leash attachment. The locating pin also allows the flip open cup to swing outwardly into the open position so that liquid can be expelled into the flip open cup.

In accordance with yet another aspect, the dispensing mechanism, comprising a body and at least one straw, is submersible within the liquid reservoir. In other words, the dispensing mechanism is fully within the liquid reservoir. Depending on the volume of liquid in the liquid reservoir, the dispensing mechanism may be fully submerged in liquid.

The present teachings also include methods for using the leash attachment with a leashed animal. The method of using the leash attachment involves placing the leash through the leash hole so that the cam can secure the leash, with the leash rolling along the ridges of the cam. The liquid reservoir is filled with a liquid through the fill hole and the cap is placed on the fill hole to prevent leakage from the fill hole. Swinging the flip open cup outward from the top surface is accomplished via the locating pin. Depressing the trigger allows liquid to travel through the at least one straw to the nozzle to be expelled. Expelled liquid is directed toward the distal end of the flip open cup so that it drains down into the flip open cup. Any unused liquid is directed to the funnel to be returned to the liquid reservoir via the fill hole, and the flip open cup is returned to the top surface.

The leash attachment has many uses. Its primary use is to provide liquid to leashed animals, allowing the animal owner to not have to carry a separate liquid bottle. The liquid exiting the nozzle can be also sprayed at the leashed animal to cool it or to redirect its attention and correct behavior. The liquid from the nozzle can be sprayed on the ground near the leashed animal's nose when it is spending too much time sniffing one spot during a walk or is distracted by another animal. The animal owner does not have to yank the leash to get the leashed animal's attention. Spraying other leashed or unleashed animals that approach the leashed animal is another use. The leash attachment can also be used to clean up messy paws or messy sidewalks by expelling liquid from the leash attachment onto the paws or ground. In addition, the leash attachment's grip provides a more comfortable feel to the user, allowing for better control of the leashed animal, especially if the leashed animal is energetic or large, as this type of animal tends to pull on the leash.

The leash attachment may be made by any conventional manufacturing method. Extrusion is a suitable method. Injection molding is another suitable method. Hard plastic or lightweight metal are appropriate materials for the leash attachment, with rubber being placed around the housing for easier handling and comfort. A portion of the inner surface of the housing, where the user's fingers grip the trigger, is textured to improve the user's grip and comfort while holding the leash attachment.

The reservoir may hold a considerable amount of liquid. 12 ounces of liquid may be accommodated in the liquid reservoir. The liquid reservoir may hold even more than 12 ounces of liquid by increasing the size of the housing. The leash attachment is able to be connected to exceptionally large animals. Indeed, animals of 200 pounds and up may be handled by the leash attachment, in addition to animals less than 200 pounds.

These and other features, aspects and advantages of the present teachings will become better understood with reference to the following description, examples and appended claims.

DETAILED DESCRIPTION

FIG. 1 refers to a perspective of a leash attachment 100. In this view, a flip open cup 160 is in the closed position, resting on a top surface 155 of a housing 105. The flip open cup 160 is attached to the housing 105. The top surface 155 is angled downward. A trigger 110 is connected to a grip 115; the trigger's deployment releases liquid from a nozzle 150. The grip 115 is for easy handling of the leash attachment 100. A cam 125 is positioned in a leash hole 135, with a second pair of detents 120 keeping the cam 125 in place when there is no leash attached to the leash attachment 100. Ridges 130 are along the outer surface of the cam 125, allowing for a firm and tight connection between a leash and the leash attachment 100. The ridges 130 increase the surface area of the cam 125, increasing the number of connection points between a leash and the cam 125. A funnel 140 is located beneath a fill hole, which is covered by a cap 220. When the flip open cup 160 is in the open position, liquid is expelled into it via the nozzle 150. Liquid that remains in the flip open cup 160, when the cap 220 is removed, can be drained back into the interior of the housing 105 via the funnel 140.
